Description
Lor (Lorazepam) 2 mg
Lor is a brand name product identified here as containing lorazepam. Lorazepam is a benzodiazepine medicine used for short-term relief of anxiety symptoms and for certain other clinically established uses. It acts on the central nervous system and can produce calming and sedative effects.
Active Ingredient and Medicine Class
The verified active ingredient is lorazepam, a benzodiazepine. Benzodiazepines enhance the effect of the inhibitory neurotransmitter GABA at the GABA-A receptor complex, which helps reduce excessive nervous system activity.
Established Medical Uses
Official prescribing information and PubMed sources identify lorazepam as being used for short-term relief of anxiety symptoms. Depending on the country and product label, it may also be used for anxiety-related insomnia, premedication before anesthesia, and treatment of status epilepticus. The exact approved uses depend on the local label.
How It Works
Lorazepam works by increasing the effect of GABA, the brain’s main inhibitory neurotransmitter. This reduces overactivity in the nervous system and can lessen anxiety, calm agitation, and cause sedation.
Important Safety Information
Lorazepam is a controlled benzodiazepine and can cause dependence, tolerance, misuse, and withdrawal symptoms. It should be used with caution in people with respiratory disease such as COPD or sleep apnea, and in older adults, who may be more sensitive to sedative and cognitive effects. It can also interact dangerously with opioids and other central nervous system depressants, increasing the risk of profound sedation and respiratory depression.
Possible Side Effects
Commonly reported adverse effects include sedation, dizziness, weakness, and unsteadiness. Other recognised effects include drowsiness, confusion, memory impairment, coordination problems, and, more seriously, respiratory depression, paradoxical reactions, and withdrawal symptoms after stopping treatment.
Scientific Evidence
Peer-reviewed reviews and clinical summaries support lorazepam’s established benzodiazepine effects for anxiety and related short-term clinical use. Published evidence also consistently describes its known safety profile, including sedation and dizziness as common adverse events, and the class risks of dependence and withdrawal.
